Building phase interface with enough solid-phase contact is of great importance for improving chemical reaction kinetics and depth. High dispersion of electrode materials, especially at the atomic-level, are known for high interface contact, yet their potential application in batteries is restricted due to low loading. Herein, the atomically dispersed metal Ni (Ni in Ni–N–C is 54.9 wt %) with high loading was achieved by ultrahigh N-doping carbon (N/N–C:29.5 wt %) during the discharging process of nickel sulfide, leading to good reversibility and high-capacity maintenance owing to ultrah...

Aqueous Zn-ion batteries (ZIBs) are regarded as alternatives to Li-ion batteries benefiting from both improved safety and environmental impact. The widespread application of ZIBs, however, is compromised by the lack of high-performance cathodes. Currently, only the intercalation mechanism is widely reported in aqueous ZIBs, which significantly limits cathode options. Beyond Zn-ion intercalation, we comprehensively study the conversion mechanism for Zn2+ storage and its diffusion pathway in a CuI cathode, indicating that CuI occurs a direct conversion reaction without Zn2+ intercalation due to ...

tunisia. that's footage from the meeting. they spoke about the violation that claimed 91 lives today. there was a warning for the assad regime. >> assad can still make the choice to end the violation, save lives, and spare his country from descending further into ruin. but if he continues to reject that choice, we and the syrian people will keep pressure on him until his deadly regime cracks and collapses, because it will. i'm absolutely confident of that. >> earlier today president obama called for greater pressure on assad. >> all of us who've been seeing the terrible pictures out ...

man, joseph ozment and served him with papers ordering him to be in court as well. they found him in laramie, wyoming and tried to flee. he tried to get away in his girlfriend and they served them with a sympathy. the pair were planning to get married and invitations gone out. there were hints of thinking of living on the land and not settling down. and there were hints they might have a small private ceremony to take place at an undisclosed time, date and location. attorney general jim lahood is joining us and no love lost and calls it political ly motivated and blamed the departmen...

pardon more than two dozen criminals. dr 300 criminals. and four convicted killers, all worked at the governor's mansion as part of a long standing program now suspended along with the pardons. before the court put the pardons on hold, those four killers walked away. three since checked in as required by the judge and expected to show up at a hearing this friday. last night, mississippi authorities tracked down this man, joseph osment and served him with papers ordering him to be in court as well. they found him in laramie, wyoming and tried to flee. he tried to get away in his girlf...
